\section{Introduction}

A focal problem today in the dynamics of globular clusters is core
collapse.  It has been predicted by theory for decades (H\`enon 1961;
%Lynden-Bell \& Wood 1968; 
Spitzer 1985; Roberts 2003), but observation has
been less alert to the phenomenon. For many years the central brightness
peak in M15 (King 1975) seemed a unique anomaly.
Then Auri\`ere (1982) suggested a central peak in NGC 6397, and a limited
photographic survey of ours (Djorgovski \& King 1984) found three more
cases, including NGC 6624, whose sharp center had often been remarked on.

\section{Observations}

% The command \htmladdnormallinkfoot puts the link as a
% footnote in the printed paper.  The command \htmladdnormallink with
% the same arguments will ignore the link in the printed copy.

All our observations were short direct exposures with
\htmladdnormallinkfoot{CCD's}{http://www.noao.edu/}.

\begin{enumerate}
\item At Lick Observatory we used a TI 500$\times$500 chip 
and a GEC 575$\times$385, on the 1-m Nickel reflector.  The only
filter available at Lick was red.
\item At CTIO we used a GEC 575$\times$385, with
$B, V,$ and $R$ filters, and an RCA 512$\times$320, with $U, B, V, R,$
and $I$ filters, on the 1.5-m reflector. In the CTIO observations we
tried to concentrate on the shortest practicable wavelengths; but
faintness, reddening, and poor short-wavelength sensitivity often kept
us from observing in $U$ or even in $B$.
\end{enumerate}

All four cameras had scales of the order of 0\farcs4 pixel$^{-1}$, and our
field sizes were around 3\arcmin.
%
The CCD images are unfortunately not always suitable, for very poor
clusters or for clusters with large cores.  Since the latter are
easily studied by other means, we augmented our own CCD profiles by
collecting from the literature a number of star-count profiles (King
et al.\ 1968; Peterson 1976; Ortolani et al.\ 1985) as well as
photoelectric profiles (King 1966) and electronographic profiles (Kron,
Hewitt, \& Wasserman 1984).  In a few cases we judged normality by eye estimates on
one of the Sky Surveys.

% In this section, we see the use of the \subsection command to set off
% an independent subsection.  We only have one in this example; in 
% general there should be more than one.

\section{Helicity Amplitudes}

It has been realized that helicity amplitudes provide a convenient
means for Feynman-diagram evaluations.  These amplitude-level
techniques are particularly convenient for calculations involving many
Feynman diagrams, where the usual trace techniques for the amplitude
squared becomes unwieldy.  Our calculations use the helicity
techniques developed by other authors (Hagiwara \& Zeppenfeld 1986);
we briefly summarize below.

\subsection{Formalism} \label{hairymath}

% We show the use of several of the displayed math environments
% described in the User Guide, and you get a healthy dose of
% mathematical typesetting examples.  Also, observe the use of the LaTeX
% \label command after the \subsection to give a symbolic tag to the
% subsection for cross-referencing in a \ref command.  LaTeX
% automatically numbers the sections, equations, tables, etc. as it
% goes, so in general you don't know what number something is going to
% have.  We'll refer to the "hairymath" section a little later.

A tree-level amplitude in $e^+e^-$ collisions can be expressed in
terms of fermion strings of the form
\begin{equation}
\bar v(p_2,\sigma_2)P_{-\tau}\not\!a_1\not\!a_2\cdots
\not\!a_nu(p_1,\sigma_1)\;,
\end{equation}
where $p$ and $\sigma$ label the initial $e^{\pm}$ four-momenta and
helicities $(\sigma = \pm 1)$, $\not\!a_i=a^\mu_i\gamma_\mu$, and
$P_\tau=\frac{1}{2}(1+\tau\gamma_5)$ is a chirality projection
operator $(\tau = \pm1)$.  The $a^\mu_i$ may be formed from particle
four-momenta, gauge-boson polarization vectors or fermion strings with
an uncontracted Lorentz index associated with final-state fermions.

\subsubsection{Weyl spinors}

The Weyl spinors are given in terms of helicity eigenstates
$\chi_\lambda(p)$ with $\lambda=\pm1$ by
\begin{eqnarray}
u(p,\lambda)_\pm & = & (E\pm\lambda|{\bf p}|)^{1/2}\chi_\lambda(p)\;,
\nonumber \\ & & \\
v(p,\lambda)_\pm & = & \pm\lambda(E\mp\lambda|{\bf p}|)^{1/2}\chi
_{-\lambda}(p) \nonumber
\end{eqnarray}

% In these sections, we see some additional math-related markup, and we
% have references to one of the tables (occurs later in the document)
% and the "hairymath" section immediately preceding this one.
%
% In the second paragraph, note the use of in-text math ($stuff$) including
% a couple of the miscellaneous symbol commands defined in the macro package.
%
% This is the last section of the paper, so there is an \acknowledgments
% section at the end of the main body.

\section{Floating Material and So Forth}

Consider a task that computes profile parameters for a modified
Lorentzian of the form
\begin{equation}
I = \frac{1}{1 + d_{1}^{P (1 + d_{2} )}}
\end{equation}
where
\begin{displaymath}
d_{1} = \sqrt{ \left( \begin{array}{c} \frac{x_{1}}{R_{maj}} 
\end{array} \right) ^{2} + 
\left( \begin{array}{c} \frac{y_{1}}{R_{min}} \end{array} \right) ^{2} }
\end{displaymath}
\begin{displaymath}
d_{2} = \sqrt{ \left( \begin{array}{c} \frac{x_{1}}{P R_{maj}}
\end{array} \right) ^{2} + 
\left( \begin{array}{c} \frac{y_{1}}{P R_{min}} \end{array} \right) ^{2} }
\end{displaymath}
\[x_{1} = (x - x_{0}) \cos \Theta + (y - y_{0}) \sin \Theta \]
\[y_{1} = -(x - x_{0}) \sin \Theta + (y - y_{0}) \cos \Theta \]

In these expressions $x_{0}$,$y_{0}$ is the star center, and $\Theta$
is the angle with the $x$ axis.  Results of this task are shown in
Table~\ref{O4.1-tbl-1}.  It is not clear how these sorts of analyses may
affect determination of $M_{\sun}$ and $M_{\earth}$, but the
assumption is that the alternate results should be less than 90\deg\
out of phase with previous values.

\begin{itemize}
\item Note that enumerated lists work as expected, with
proper margins and indentation. The list at the
beginning of the paper is enumerated.
\item Itemized lists also work as expected, with proper
margins and indentation.  This list is itemized.
\end{itemize}

% Tables can be generated using the deluxetable environment, the same
% environment used in the AASTeX macro package.  Here \scriptsize
% was used to force the table to fit on the printed page.
%
% Column headings are specified within a \tablehead command, using the
% \colhead command to specify each column heading (or the LaTex command
% \multicolumn may be used).  The data is entered between the \startdata
% and \enddata commands.  Use the & as a column delimiter and end each
% data line with \nl.  For details see the User Guide.

\end{deluxetable}

% In the figure environment the \caption command should contain only the 
% caption text.  The "Figure N." identification is generated by the
% \caption command on its own.
%
% In this example we insert the \epscale command before the \plotone
% command to override the default scaling of the figure. 
%
% You cannot use footnotes within figures.

This paragraph has been placed here to illustrate the
relationship between floating elements and running text.  A sample
figure appears in Figure~\ref{O4.1-fig-1}.
\begin{figure}[t]
\epsscale{0.70}
\plotone{figure.eps}
\caption{A particularly ghostly figure.} \label{O4.1-fig-1}
\end{figure}
We insert the figure in the text file immediately after the sentence
in which it is called out; this happens to be in the middle of a
paragraph.  Notice that this paragraph continues on after the 
\texttt{figure} environment is closed. The typeset text of the paragraph will
not be broken by the figure; rather, the figure will be floated to
a place (top or bottom of a page, possibly after the
paragraph) close to the textual material in which it is embedded in
the source file.
 
% The same tabular data presented above in the deluxetable environment is
% aligned below within the "tabular" environment. Observe
% that our tabular environment is embedded within a "center" environment,
% which is in turn inside a "table" environment.
%
% We need the table environment for autonumbering and caption generation,
% which is why it is not enough to have a centered tabular.
%
% Within the tabular environment, please note that we use no vertical
% rules, and the horizontal rules are inserted with \tableline (*not* \hline).
% Note that a couple of the column headings require special annotation, i.e.,
% footnotes for tables.  They are marked and tagged with \tablenotemark.
% \tablenotemarks could be placed on individual data entries as well,
% but try not to go berserk doing this.
%
% It is necessary to \label tables and figures *after* the \caption has been
% specified because the table/figure number is generated by \caption, not
% by \begin{whatever}.

We repeat Table~\ref{O4.1-tbl-1} which was formatted using the 
\texttt{deluxetable} environment, but this time we use the \LaTeX\ table
environment (see Table \ref{O4.1-tbl-2}).  Either table environment
is acceptable, but the \texttt{deluxetable} environment is preferred.
%
\begin{table}

%
However, reducing the text size does sacrifice the readability of the
numbers in the table, and the table environment does allow more
control over the spacing of the columns.  
In each table, note the use of the math mode minus
sign (\texttt{\$-\$}) instead of the text mode dash.

% Finally, we have a little acknowledgments section. Do NOT place 
% acknowledgments in a separate \section.
